Next Fetch Position
The SQL Native Client OLE DB provider keeps track of the next fetch position so that a sequence of calls to the GetNextRows method (without skips, changes of direction, or intervening calls to the FindNextRow, Seek, or RestartPosition methods) reads the whole rowset without skipping or repeating any row. The next fetch position is changed either by calling IRowset::GetNextRows, IRowset::RestartPosition, or IRowsetIndex::Seek, or by calling FindNextRow with a null pBookmark value. Calling FindNextRow with a nonnull pBookmark value does not affect the next fetch position.
